OPTODERM Vitamin C 15% Serum

Features & Benefits

Sodium Ascorbyl Phosphate (SAP) is a naturally occurring water-soluble derivative of Vitamin C. It is the most stable form of Vitamin C, meaning it won’t oxidise easily and is more stable and bioavailable than Magnesium Ascorbyl Phosphate (MAP), Ascorbyl Palmitate, and L-Ascorbic Acid (amongst other Vitamin C derivatives). Unlike L-Ascorbic Acid, it doesn’t like acidic environments and prefers a ‘skin friendly’ pH of around 7. It is an antioxidant that reduces oxidative stress by neutralizing free radicals, effectively slowing down the aging process and the formation of fine lines and wrinkles. It is more bioavailable than pure vitamin C since it has a salt molecule attached to it, allowing it to easily penetrate the skin’s lipid barrier. Because this form of Vitamin C is easily absorbed and utilised by the skin, it is not associated with the irritation often experienced with L-ascorbic acid. Our proprietary PenetrX technology facilitates even better and quicker penetration. Furthermore, a lower concentration is needed for the same results, which also leads to less irritation. We use 15% SAP in OptoDerm Vitamin C Serum, which is equivalent to a much higher concentration of L-ascorbic acid, due to its increased bioavailablity. Proline and Lysine are converted to hydroxyproline and hydroxylysine in the skin – a reaction facilitated by ascorbic acid. These are important molecules in the formation and stability of collagen and elastin respectively.
